Starting a trucking business involves more than purchasing a vehicle and finding freight.
A new motor carrier may need a USDOT number, federal operating authority, insurance filings, state credentials, driver qualification records, and an ongoing safety management program.
The requirements depend on what the business transports, where it operates, and which vehicles it uses.
This guide explains the main compliance steps for new owner-operators, expanding fleets, and other commercial vehicle businesses in 2026.
Who Should Use This Guide?
This guide is intended for new owner-operators, companies purchasing their first commercial truck, existing carriers adding vehicles, and businesses operating commercial vehicles as part of their regular activities.
It also provides a starting point for companies reviewing their DOT compliance responsibilities.
Federal and state requirements are not identical, so each operation should be evaluated individually.
Step 1: Determine Whether You Need a USDOT Number
A USDOT number identifies a business in FMCSA’s registration and safety monitoring systems.
For interstate operations, federal USDOT registration generally applies when a vehicle or combination has a GVWR, GCWR, GVW, or GCW of at least 10,001 pounds.
Other triggers include transporting more than eight passengers, including the driver, for compensation; transporting more than 15 passengers, including the driver, without compensation; and transporting specified hazardous materials.
Some intrastate businesses must register under state rules even when federal interstate criteria do not apply.
A USDOT number is assigned to the business, not separately to every truck.
Step 2: Establish the Business
Choose the appropriate business structure, such as a sole proprietorship, partnership, LLC, or corporation.
Complete applicable state formation requirements.
Obtain an employer identification number when required.
Confirm the legal name and address that will be used on federal registrations, insurance, and business contracts.
The registered entity should be consistent across these records.
Step 3: Apply Through FMCSA’s Current Registration System
FMCSA launched Motus on May 19, 2026, replacing legacy registration workflows for applicable transactions.
New applicants can use Motus to apply for a USDOT number and the registrations or operating authority relevant to their business.
The system uses individual accounts, The public’s one account for government. | Login.gov identity verification, and company-account management.
Visit MOTUS and follow current FMCSA instructions.
A new USDOT number does not, by itself, authorize every type of interstate for-hire transportation.
Step 4: Determine Whether Operating Authority Is Required
Federal operating authority is separate from USDOT registration.
Many interstate for-hire carriers transporting regulated property or passengers require authority.
Private carriers and certain exempt operations may not need the same authority.
Brokers and freight forwarders have their own authority categories.
MC, FF, and MX docket identifiers have not all been discontinued merely because FMCSA introduced Motus.
Verify the applicable authority and its effective status before beginning regulated operations.
Step 5: Complete Applicable BOC-3 Requirements
Businesses required to designate process agents must complete the applicable BOC-3 filing.
Process agents accept legal documents on behalf of the registered business.
A properly authorized blanket company or process-agent provider handles the filing.
Not every USDOT registrant has identical BOC-3 requirements.
Step 6: Arrange the Correct Insurance
Insurance requirements depend on the business’s authority type, vehicles, cargo, and operations.
For example, a qualifying interstate for-hire property carrier operating vehicles weighing at least 10,001 pounds generally has a $750,000 federal minimum public liability requirement for nonhazardous property transportation.
Certain hazardous materials operations have higher minimums.
Passenger carrier requirements vary by seating capacity and other factors.
Household goods carriers may have additional cargo insurance requirements.
Your insurer or other authorized provider generally submits required financial responsibility filings to FMCSA.
Do not assume every operation uses the same insurance form or minimum.
Step 7: Verify Authority Before Dispatch
A submitted application does not equal granted authority.
Confirm that FMCSA has granted the authority required for the proposed operation and that all required insurance and process-agent filings are effective.
Do not rely on a universal number of days after submission.
Check the actual registration and authority record before accepting regulated loads.
Step 8: Prepare for the New Entrant Safety Program
New interstate motor carriers generally enter FMCSA’s 18-month New Entrant Safety Assurance Program.
The agency monitors safety performance and conducts a safety audit.
FMCSA states that a new entrant safety audit is normally conducted within 12 months after operations begin.
Carriers should establish their safety controls before operating, rather than waiting for an audit notice.
Step 9: Maintain Driver Qualification Records
Motor carriers must verify that their drivers are qualified for the assigned work.
Depending on the operation, records may include employment applications, driving-history inquiries, CDL information, medical qualification, and required periodic reviews.
Driver qualification rules can apply even when the driver does not need a CDL.
Maintain records according to the applicable retention requirements.
Step 10: Establish Drug and Alcohol Compliance
Carriers employing drivers subject to FMCSA’s CDL drug and alcohol testing rules must establish an appropriate testing program.
Applicable requirements include pre-employment testing, random testing, Clearinghouse queries, and reporting.
An owner-operator subject to these rules may need a consortium or third-party administrator arrangement.
The Clearinghouse does not replace the testing program.
Step 11: Manage Hours of Service and ELDs
Covered drivers must follow applicable hours-of-service requirements.
Many operations also require electronic logging devices, although exemptions exist.
Train drivers on the rules relevant to their routes and work.
Maintain records of duty status and supporting documents when required.
Step 12: Maintain Vehicles and Inspection Records
Create a systematic vehicle inspection, repair, and maintenance program.
Covered vehicles generally require a qualifying periodic inspection at least every 12 months.
Address safety defects promptly.
Ensure drivers complete required pre-trip reviews and applicable post-trip defect reports.
A roadside inspection does not automatically replace the annual periodic inspection.
Step 13: Mark Commercial Vehicles Correctly
Under federal marking requirements, covered self-propelled commercial motor vehicles generally must display the carrier’s required identification and USDOT number on both sides.
Markings must contrast with the vehicle and be legible from 50 feet while stationary in daylight.
There is no universal federal two-inch letter-height rule.
Additional state or operation-specific marking rules may apply.
Step 14: Determine IRP and IFTA Requirements
The International Registration Plan and International Fuel Tax Agreement apply to qualifying vehicles and operations.
Not every interstate commercial vehicle qualifies.
Vehicle weight, axle count, jurisdictions, and operating patterns matter.
Review each program separately before obtaining credentials.
Step 15: Complete UCR When Required
Unified Carrier Registration is an annual registration and fee program for covered interstate transportation entities.
Qualifying carriers, private motor carriers of property, brokers, freight forwarders, and leasing companies may be covered.
UCR is separate from USDOT registration and operating authority.
The 2027 UCR registration season opened October 1, 2026, and covered entities must pay before January 1, 2027.
Step 16: Keep the MCS-150 Current
The MCS-150 maintains company information such as legal name, addresses, operations, power units, drivers, and mileage.
Reportable changes generally must be updated within 30 days.
The normal biennial schedule is determined by the final two digits of the USDOT number.
FMCSA temporarily suspended enforcement of biennial updates and related USDOT-number inactivation for deadlines due on or after June 1, 2026.
The underlying update obligation remains.
Step 17: Understand Registration Problems
An inactive USDOT number, revoked operating authority, and out-of-service order are different regulatory statuses.
An insurance lapse may affect authority.
A safety violation may result in an out-of-service restriction.
UCR nonpayment may lead to state enforcement.
Do not assume every problem can be corrected with an MCS-150 filing.
What If You Add Trucks to an Existing Fleet?
Review the company’s reported power-unit count, insurance schedule, vehicle registration, maintenance records, and applicable state credentials.
Determine whether the new equipment changes IRP, IFTA, or UCR calculations.
Confirm the correct vehicle markings.
A fleet expansion should trigger a compliance review, not merely an insurance change.
